To determine the number of permutations of 5 distinct numbers, we can use the formula for permutations, which is given by n!, where n is the total number of items to arrange.
In this case, since we have 5 numbers, we calculate 5! (5 factorial). This means we multiply 5 by all the positive integers less than it:
- 5! = 5 × 4 × 3 × 2 × 1
- 5! = 120
This means there are 120 different ways to arrange 5 distinct numbers.
